Abstract: In order to hang sheet material, such as an aluminum skin section of an aircraft, during processing thereof, a plurality of hangers are provided, for releasably engaging an upper edge of the sheet material at spaced locations therealong so as to provide, in one mode, points of attachment for connection of the sheet material to an overhead support or hoist, and to provide in another mode, lateral abuttments for straddling a pair of elevated, spaced parallel rails to hand the sheet material therebetween while awaiting the next processing operation. The body of the hanger has an inverted Y-shape wherein the downwardly oriented leg portions are separated by a vertical slot for receiving the upper edge of the sheet. A releasable shear pin held in the legs of the hanger body is passed through a pin receiving hole provided in the sheet adjacent the upper edge thereof when such sheet edge is inserted in the hanger slot.
